' pplication filed October .30, 1922 Serial no. 597,885.

T all whomit may concern: i

Be it known that CLi v'ToN A. SPINDLER, a citizen of the United States; residing at "Mariettm'in the county of lVashington and v State of Ohio, has invented certain new and useful Improvements in Feed'Valves for Boilers, of which the following is, a specificationf p v hlyrinvention relates to boiler feed valves andits principal object is' toprovide a feed valve wherein the water supply from the boiler may be out offto obviate freezing of Cthe valve in'cold weather. a

It is'a'lso-an obiect of the invention to provideifa feed valve which will permit eitheri side thereof to be used for a blowotf andfdrain plug andis so constructed as to eliminate an auxiliary blowofl, and nipple.

: "The-invention" also contemplates avalve ,9 which maybe constructed and sold at'a comparatively. smallcost and provides a valve an dznipple having a blowofi.

These and likeobjects will be better unle rsto,od as the description p1 oceeds and as 'is'specifically pointed out in the appended v 1 Referring to thefacoompanylngdrawing -iwlnch formsa part of this, specification,

taken onlines 22 of'Fig. 1.

Figure 3isan elevation of the valve {is-- sociatedlwith, aiboiler, and

Figure llis 'a horizontal-sectional view taken on'lines 4+4 of Fig. 1;

Referring'to the drawing in detail wherein like characters of reference denote like parts throughout the several views, the numeral 5' designates the valve casingor barrel having laterally extending n pples, 6 at diametrically opposite points. 'One of these nipples is adapted to be connected to the boiler feed Water supply while the other constitutes the-,lolowoil; The lower end "of ,the valve I casing 01- barrel is provided'with an exterior" screw thread-7 which is threaded to the V -aboiler while the upper end is provided with n v "a packing glandfi in which a vvalve sterul) Figure 1 isa verticalsectional view;-of a fblowofl" valve constructed in accordancewith myinveiit-ion. v -Fignre2 is' ahorizontal sectional view extends the latter passing longitudinally through the barrel or casing 5.

Supported within the valve casing .or bar-f rel 5' at the upper end thereof is a spider 9 to which an internally'threaded sleeve 10 is secured and which t-hreadedly'receive's the valve stem 9. A similar spider 11 is arran ed inthe valvecasing or barrel 5 adjacent the lower end thereof and is provided withia central guide 12 through whioh th'e valve stem 9 passes.

A'coni'cal valve element 13 is carried by the lower end of the valve stem 9 land is adapted toseat on a seat 14 formed in the lower end of the valve casing or barrel 5.

From the: disclosureit' will be obvious that I have provided a simple and inexpensive blowofi' valve either nipple of which may be; used, as ablowoif or connected with the'feed water supply. Also my improved valve will eliminate freezing; duringcold weather by "operating the valve to seat on'the' seat 14. j

,Wliile I have shown and described the preferred form of my invention,, I realize thatvarious minor changes may be resorted lZO,'Wltl10t1lJ departing from the spirit and scope of the invention as claimed; therefore, I

combination and arrangement of parts;

} lVhat I claim as new and desire to secure by Letters Patent is I Y 7' In combination with a boiler, a valvebar- I donot wish to limit. myseltto the exact details of construction shown,'nor to the;

rel provided with a valve: seat at one end, a

plug thr eaded'in the upper end :of the barrel, a packing clamp fitted thereon, spiders arranged within the barrel, one of said spiders having an internally threaded sleeve,

a threadedjstem passing through the plug, the threaded sleeveand the said spiders, a

,valveoarried by the lower end of the stem vand engageable with the valve seat, and laterally disposed nipples on the barrel posi tioned at substantially right angles to the barrel and adapted to beconneoted-tothe boiler feed water supply, forming aicutofi means to prevent freezing in cold weather, substantially as described. v

In testimony whereof I afiix my. signature;

CLINTGN A. SPINDLER.
